▎ 摘　　要

NOVELTY - Charge-transfer controlled two-dimensional (2D) device includes a 2D active conducting material, a 2D charge transfer source material, and at least one overlapping portion. The 2D active conducting material overlaps the 2D charge transfer source material including at least one edge of the 2D charge transfer source material. USE - Charge-transfer controlled two-dimensional (2D) device. ADVANTAGE - The charge-transfer controlled two-dimensional (2D) device gains control of the flow of electrical current through atomically thin materials for applications including but not limited to photovoltaics and computing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for controlling charge transfer in 2D materials, which involves providing a 2D active conducting material, providing a 2D charge transfer source material, and positioning the 2D active conducting material to overlap one portion of the 2D charge transfer source material including at least one edge of the 2D charge transfer source material.
